Navigation submenu disappears after first slider changes (1 post)

Hello,
I am really new to web development. I am working on a wordpress template. I made some changes to the style sheet to get my logo positioned at the top of my site, then the navigation and footer format got messed up.
The navigation menu looks great when you first pull up the slide. After the first slide changes though the navigation drop downs disappear and cannot be accessed unless I click on one of the top navigation menus and access via a page without a slider. Please help! My template company won't help me.
Also after I made the changes to get the logo up there my formatting for my footer stopped working. It was 3 menus next to each other running from left to right. Now it is just a list of links running vertically down the page.
This is my first time to post so please forgive me if I forget any information.
